The activities here offer you a chance to reflect about what you have learned during this chapter.
As you work, look for concepts that you feel very comfortable with, ideas that you would like to learn more about, and topics you need more help with.

By the end of the period, I will apply different problem‑solving strategies and relect on what I have learned in this chapter.
I will demonstrate this by completing Four‑Square notes and by solving problems in a pair/group activity.

SUMMARIZING MY UNDERSTANDINGThis section gives you an opportunity to show what you know about properties of triangles and applying the Pythagorean Theorem, two of the main ideas of this chapter.
Triangular Treasure HuntJasmine and Mason are spending the summer with their Uncle Simon. He lives in an old castle that has many interesting doors, not all of which are rectangles. One day, while looking through the books in the castle library, Jasmine found an unusual piece of paper in a book. “Look, Mason! This looks like some kind of a treasure map,” she exclaimed. Mason looked at the paper and read, “A valuable secret is hidden inside. But beware – danger lurks behind the other doors. Only those who can follow the clues will succeed in the search.” He also saw that it had a series of clues and pictures of triangular doors. Read the clues below and, with your team, help Jasmine and Mason find the secret door and the treasure.
• My sides are not congruent.• My angles are not congruent.• I am similar to another door.• One of my sides is units long.
a) Look at the doors on the Chapter 9 Closure Resource Page.b) Using what you have learned in this chapter, decide which door is the secret door. Justify your answer. c) List the triangles that were not the secret door and justify why each did not fit the clues.

CL 9160. Casey was building a rectangular pen for his pigs. He has 62 feet of fencing. The length of his pen is 9 feet longer than the width. Write and solve an equation to find the dimensions of the pen.

CL 9161. Clay and his friend Lacey are making cookies for the school dance. Clay started early and has already made 3 dozen cookies. He can make an additional 2 dozen cookies an hour. Lacey has not started making cookies yet, but she has a bigger oven and can make 4 dozen cookies an hour. If Lacey starts baking her cookies right away, how long will it take for her to have made as many cookies as Clay? How many cookies will they each have made?

WHAT TOOLS CAN I USE?You have several tools and references available to help support your learning – your teacher, your study team, your math book, and your Toolkit, to name only a few. At the end of each chapter you will have an opportunity to review your Toolkit for completeness as well as to revise or update it to better reflect your current understanding of big ideas.
The main elements of your Toolkit should be your Learning Logs, Math Notes, and the vocabulary used in this chapter. Math words that are new to this chapter appear in bold in the text. Refer to the lists provided below and follow your teacher’s instructions to revise your Toolkit, which will help make it a useful reference for you as you complete this chapter and prepare to begin the next one.Learning Log Entries
